Regardless of the project, my Laser stops engraving after only approx 2 minutes - it cuts just fine.
The issue seems to only be with the engraving.
I’m using Lightburn 1.07.8,
The laptop has been set to not close usb com’s, for energy saving.
Attached is the latest test file
Bass 3mm 3k20 3k30.lbrn2 (36.9 KB)
This file starts, and then stops within 2 minutes
I’m using a Falcon Pro 10W, my laptop is a Win11 machine
Although grbl machines aren’t my forte, you really need to give us more information. When it stops does it loose power..?
Usually the console in Lightburn will give you some kind of error message or think it’s completed the job. The console may not be visible, you may have to click on Window on the top tool bar to enable the console. It will be a tab in the cut/layer window.
I don’t see anything in your project file that I think could cause an issue.. all setting seem reasonable.
You are only giving it <15mm to get to speed, don’t know if grbl is smart enough to flag this as an error. You’d have to figure out what your acceleration values are to use any of the on-line calculators.
If your speed is set for 50mm/s with an acceleration value of 50mm/s^2, then you need about 25mm to get to speed. These are older machines, so you acceleration values will likely be different. If you use the console and type $$ it should echo all of these variables.
There is a relatively easy way to check, moving the image >25mm away from the edge, as long as it has time to speed up/change directions and slow down. It wouldn’t hurt to make it further away to ensure you’re not too close.
Ok - the machine after stopping is indicating job is done (power light on machine, flashes slowly), no error messages on the console
Using the run time, on my led machine, it estimates it a 2:32. It sounds like it’s doing the job..
What is it doing for those two minutes? Movement? Anything?
Yes, the head does start to engrave, but stops after ~ 2 mins, on this particular design its as shown, and always at this point (on this design)
I think we need to call on other that have better skills with grbl than I do. I’m hoping @misken can shed some light on this issue.
I don’t know what to tell you at this point.
OK - thks for the suggestions, I just re-installed the driver and connection, and the engraving seems to work now - will try a cut shortly
Great, couldn’t be better news…
Keep us updated.
Have fun
